Light Housings Kydex acrylic PVC in 12 mm for Rail Transit Interiors – Formed to Drawing

These Kydex acrylic PVC light housings are thick gauge vacuum formed parts supplied to drawing for rail transit interiors. They are formed from Kydex acrylic PVC sheet at 12 mm, trimmed on 5-axis routers and inspected against the drawing before packing. Buyers choose this route where a metal fabrication is too heavy, or where injection moulding tooling cannot be justified for the volume.

Product specification

Key features

• One piece shell replaces a fabrication, so assembly hours drop
• Kydex acrylic PVC keeps the weight down while stiffness is held through the formed shape
• Anti static coating finish as standard, further finishes on request
• Trimmed on 5-axis routers, so mounting holes and cut outs match the drawing
• Tooling stored against the part number for repeat and spare orders
• material certificates with every batch

Typical applications

• seat shells
• ceiling end caps
• luggage rack trays
• wall panels
• light housings used across general rail transit interiors builds

How it is made

1. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
2. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
3. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
4. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
5. The part cools on a jig so the shape is held while the material stabilises.

Material: Kydex acrylic PVC

Kydex acrylic PVC sheet is specified for interior trim that must resist scuffing and meet fire, smoke and toxicity rules.

Design notes

• hold the draw ratio near 1:1 for deep parts, or specify plug assist
• avoid sharp steps in the mould, which show as chill marks on the finished surface
• call out the finish on the drawing: mould texture, paint, or as-formed gloss
• plan the trim line on a flat face so the router can hold tolerance

Finishing and assembly options

• anti static coating
• soft touch coating
• satin finish
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

Sheet thickness is checked on the formed part at the points shown on the drawing, and the readings go into the report. First article inspection covers critical dimensions, wall thickness, colour and texture against the approved sample.

• PPAP or ISIR on request
• ISO 9001 quality system
• dimension reports with every release

Packing and delivery

Large panels are crated in made to measure wooden cases with corner protection. Standard lead time to first article is 3–4 weeks, and repeat releases ship against stored tooling without a new proving run.

Frequently asked questions

How fast is the first article?

Seven to fifteen working days from drawing release for sample tooling, with production tooling in three to four weeks.

Can you make it in another material?

Any grade in this family can be swapped in. Send the requirement and the material will be quoted with the price difference shown.

Are spare parts available later?

Tooling is stored against the part number for the life of the programme, so replacements or spare panels can be released at any time.
